I'm not much of an expert on prams because I generally don't sell them in my shop as a rule. I have just purchased a Valco Runabout with a toddler seat for myself after doing some research.

Valco - The thing to note with Valcos is they are wide, so don't fit through all checkout aisles, a lot of mums have to use the wheelchair aisle to fit through. The benefit is because they are wide, they are less likely to topple over, especially with a toddler seat (something to keep in mind for the future).

BeemerQ - I've heard good things, but was told by a Babyco salesperson that they aren't suitable with a toddler seat because they topple easily.

Phil & Teds - I don't know a lot, but I think they are narrower than the Valco Runabout and generally a good pram. The toddler seat function is a completely different setup, but I have heard nothing bad about it. Be warned, they are VERY expensive!

You may be able to Google some reviews on the prams you are interested in. Sorry I can't be of more help!
